IMPROVEMENT IN WINDOW-SCREENS.

The Schedule aimed to in these LettenPatont and making put of the semi.

To, all whom it may concern Be it known that I, BENJAMIN GIRQUX, ofChicago, in the county'of Cook and State of Illinois, have'invented anew and improved Window-Screen; and I do hereby declare the following tobe a 'full, clear, and exact description thereof, reference being bad tothe accompanying drawing forming part of this specification.

Figure 1 is'a front elevation of a window with part of the sill brokenaway to show the application of my improvet screen.

Fignre 21is a detatched sectional viewof the baseof the window,,sbowingthe spring and the screenrollerin section.

.Similar letters of reference indicate corresponding parts in theseveral figures of the drawing.

My invention has for its object to provide a windowscreen which shall beraised and lowered by the sash, whereby dust, insects, &c., are excludedfrom dwellings, railway cars, vessels, 850., in the most effectualmanher; and to this end,

The invention consists in a screen of gauze having its upper edgesecured to the bottom rail of the lower sash, and its lower end attachedto a spring roller screen when the window-sash is raised, and to rollthe same upon the roller when the window is lowered.

The screen passes directly through a slot in the 'window-sill made forthe purpose,'so that, when the sash is lowered, it shall rest upon thesill covering the slot, the screen being contained in the base beneaththe casing. To facilitate the attachment of the roller andscreen to thewindow-casing the base is made in the form of a box, and its front G isadapted for removal by means of thumb-screws H, as shown, or otherconvenient devices.

If desired, the coiled springs maybe dispensed with and spiral springsemployed'for the same purpose, but arranged longitudinally within theeasement.

If desired, also, a screen may be applied to the up per sash with itsroller in the top of the window-cas ing. In this case the tension of theroller-springs will balance the weight of the sash when the latter islowered.

Having thus described my invention,

What-l claim as new is- In combination with the window-sash, the screenD passing through the slotted top or sill of the casing, and the springroller E arranged in the box above or below the casing, snbstantiallv'asdescribed, for the purpose specified. V The above specification of myinvention signed by me this 4th day of September, 1870.
